What is a proxy and what is it for?
A proxy is an intermediate computer that is used in the communication of two others. The information (usually on the Internet) goes directly between one computer and another. Through a proxy, the information goes first to the intermediate computer (proxy), and it is sent to the destination computer, so there is no direct connection between the first and the last.
In almost all cases, the proxy only serves to hide, and most often these proxies are used to perform illegal practices (spam, fraud, etc.). That is why, it is always desirable to avoid proxies, especially when they are forums, chat or social media servers.In other cases (this minority of cases), it is when a proxy is used as an interconnection between many computers on a network, with the Internet. In that case, you can use a proxy because of the added advantages it has.
How do you mount a proxy?Well, with a dynamic IP, a server, a domain, configure the server (Linux or Windows) for it, a simple web page, advertising banners and promote (advertise).Advantage
When a proxy is used in an internal network to use it as a connection between the outside (Internet) and the inside (each internal computer) has many advantages:
- Less configuration time (just configure the proxy).
- Greater security
- More efficient filtering
- In other cases the biggest advantage, without a doubt, is:
- Load. The proxy may be subjected to too much load if many computers make requests simultaneously.
- Data cache between 2 computers. Some proxies may keep copies of the transfers, which implies some interference and insecurity.
- Outdating In some proxies the most current information may be affected.
